Choose your cleansing product carefully. Brazilian curly hair still needs shampooing at least once every other week. Be sure to stay away from ingredients such as sulfates and silicones. The latter are synthetic additives that weigh hair down and are difficult to remove without the use of harsh ingredients. On the other hand, sulfate acidity raises the hair cuticle while removing dirt buildup, which promotes frizzing. As much as possible, steer clear of products that contain these ingredients
